A Guide to Increasing Conception Rates and Ovulation


We all know that breeding season is challenging. When a mare is difficult to breed, it can make the season more labor intensive and result in losses not only emotionally but financially. Horses are not the most fertile animals: conceptions rates only average about 60%, so it’s crucial that a mare is healthy. Optimal health is essential to achieve maximum reproductive efficiency. Releira is a feed through supplement designed to support reproductive health in mares and stallions, as well as provide unborn foals with nutritional support.

In addition to vitamin D3 and vitamin E, Releira® also contains docosahexaenoic acid (DHA) in the form of long-chain, polyunsaturated omega-3 fatty acids fundamental to proper foal development. The DHA in Releira™ originates from an all-vegetarian, micro-algae source - not fish oil - so it's free of oceanic pollutants and toxins and, as a result, is more palatable to horses.

Releira added to a mare's normal diet 90 to 120 days prior to breeding season can increase a mare's reproductive function and aid in her ability to "catch" when bred. It also supports the foal’s cognitive development as well as proper eye and brain development in-utero and while nursing. A proper balance between omega-6 and omega-3 fatty acids in the diet is important for reproductive performance. In broodmares, DHA/omega-3 fatty acid supplementation may beneficially influence the size of ovarian follicles, ovulation rate, progesterone production, and gestation length. These are all essential functions for a healthy and productive broodmare and a successful pregnancy.

Ovarian follicles are the predecessors to embryos. DHA promotes the growth of ovarian follicles, thereby facilitating oogenesis and the maturation of oocytes. An increase in the ovulation rate means that you will have more chances to breed your mare, as she will cycle more frequently. The more chances you have to breed her, the more likely she is to conceive. DHA may increase the production of progesterone. Progesterone is the hormone responsible for preparing the uterus for implantation of the embryo and it is crucial for a successful pregnancy. DHA has also been shown to increase gestation length. An increased gestation length provides more time for the fetus to develop and reduces the risk of preterm birth.

Another key way to maximize your mare’s breeding potential is to start as early as possible. The earlier you start, the more cycles you will have to achieve a successful breeding. This requires careful planning early in the season, especially since it is most beneficial to start feeding Releira 90 to 120 days prior to breeding. However, it is worth the planning as Releira can provide much needed support before, during, and after pregnancy. The human grade DHA contained in Releira supports mares by reducing uterine inflammation and supporting cellular health in oocytes.

While the mare’s health is absolutely critical to a successful breeding season, the stallion’s health is equally critical. Releira helps support healthy sperm production and motility. Adding Releira to your stud’s diet provides him with DHA which has been shown to be essential for proper sperm formation.

During sperm development, a pointy cap is formed on the head called an acrosome. The acrosome is made up of many tiny vesicles of membrane. These vesicles contain the enzymes needed for penetrating the egg. However, if DHA isn’t available, these vesicles never fuse together and the acrosome never fully forms which inhibits the sperm from fully maturing.

DHA has also been shown to be a part of the process that regulates sperm motility. It is most commonly believed that the biophysical properties of DHA contribute to the membrane fluidity and flexibility needed for motility of the sperm. It is also thought that DHA is involved in regulating free fatty acid utilization by sperm or it can be metabolized to other lipid-like compounds. Free fatty acid utilization is essential for healthy sperm maturation.

Adding Releira to your stallion’s diet has other benefits as well. Not only does DHA support healthy sperm production but it also supports proper eye and brain development. Enhanced cognitive ability can improve trainability and performance. DHA also supports amazing hair coat. So he’ll not only perform great, but he’ll look great too!

One of the most nerve wracking things about the breeding season is conception. It seems like once the mare has conceived, you can breathe easier. Unfortunately, conception rates in horses aren’t the highest and every mare that does not conceive is a financial loss for this breeding season. Releira is [M1] most comprehensive supplement for the breeding season. It supports the mare and her ability to conceive and carry her foal, it supports the stallion’s sperm production and motility, and DHA supports the foal from gestation through nursing. So support your mare, your stallion and your unborn foal with Releira and the beneficial DHA it provides.
